Police are appealing for witnesses of what they are calling a 'heinous crime' in which a 9-year-old boy was left too frightened to stay at home after an axe was held to his throat in Great Barr.
The attack happened around 8pm on Monday evening when several masked men broke into the boy's family home on Newton Road armed with sledgehammers and an axe.
The robbers threatened the family while making demands for cash and keys to the sports cars parked on the drive.
The father Rajinder Auluk handed over two sets of keys, one for a Nissan Pulsar GT the other for Mercedes CLK.
Police say the offenders left the Mercedes on the road outside the house. The Nissan was seen driving away before a black Audi joined the car and drove towards Sutton Coldfield.
